MAC address vendor

Keysight Technologies, Inc. — 4 confirmed MA-L prefixes

Primary prefix
00:1B:6E
Block
MA-L
Status
Active

Summary

// what this is
Keysight Technologies is registered to MAC prefix 00:1B:6E and 3 more in the IEEE OUI database. When a device's MAC address begins with 00:1B:6E, that block was registered by Keysight Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Multiple independent OUI assignments plus a corroborated network-test product line and verifiable public-company identity indicate a substantive registration, not a bare shell. A Keysight OUI reliably identifies test/lab equipment rather than consumer devices.

About this vendor.

Updated  ·  Confidence: High

A MAC address beginning with 00:1B:6E, 80:09:02, 00:1A:C5, or 2C:D1:DA belongs to Keysight Technologies, Inc., and typically identifies network and protocol test equipment — Ethernet traffic generators, protocol analyzers, and related lab or production-test hardware — rather than a consumer device.

Keysight is the November 2014 spin-off of Agilent Technologies' electronic-measurement business, itself tracing back to the original Hewlett-Packard test-and-measurement division founded in 1939. The company trades publicly as NYSE: KEYS and employed roughly 9,500 people across 30 countries at spin-off, headquartered at 1400 Fountaingrove Parkway, Santa Rosa, CA.

IEEE's registry ties three of the four confirmed prefixes (00:1B:6E, 80:09:02, 00:1A:C5) to that Santa Rosa address, while the fourth (2C:D1:DA) is registered to a Honolulu, HI address. That is likely a registration agent or an acquired-business address rather than a second corporate site — flagged here as a data quirk, not resolved.

Keysight's own product lines corroborate the ethernet allocations: its network test-hardware chassis platforms and the AresONE family generate and validate Ethernet traffic from 100GE to 800GE, alongside L2-L3 protocol test tools such as IxNetwork, IxANVL, and IxVerify — exactly the class of device that would carry a vendor-registered MAC on a physical test-equipment interface, not a shell registration.

IEEE's public OUI export carries no registration-date field. Any "date registered" shown by third-party aggregators such as maclookup.app (per-prefix dates spanning 2006-2014 for these blocks) is a database artifact of that tool's own ingestion process, not an IEEE fact, and is not recorded here as one.
